The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.
However, there has been research in this area. In germany, frankincense (boswellia serrata) is aparently considered a standard treatment for cancer in brain because it is one of the few substances believed to cross the BBB. Wormwood (Artemisia absinthium) is another possibility.owever, there has been research in this area.

Some of the smaller molecules get through, but not the whole suite of drugs intended. Doctors don't know for sure, but it seems that in order to cross the blood-brain barrier, only molecules less than 800-1000 atomic mass units (amu) in molecular weight can get through.Lipid solubility seems to be another factor which facilitates passing through the blood-brain barrier.Water soluble molecules don't usually penetrate into brain tissue, even when very small. The molecules of essential oils are all not only small, but lipid soluble as well.he American Medical Association (AMA) has said that if they could find an agent that would pass the blood-brain barrier, they would be able to find cures for ailments such as Lou Gehrig's disease, multiple sclerosis, Alzheimer's disease, and Parkinson's disease.
